It is worth noting that you can setup a lot of these parameters in the file /etc/sysctl.conf.

For example to ignore broadcasts you can set:

net/ipv4/icmp_echo_ignore_broadcasts=1

This flag will then take effect the next time you reboot, or if you run:

sysctl

(Running either "man sysctl", or "man sysctl.conf" will give more details).
